IMPROVEMENT IN GANG PEGGlNG-MACHlNE S Specification forming part of Letters Patent No. 216,926, dated June 24, 1879; application filed J anuhry 31, 1879.

i To all whom it may concern.-

Be it known that we, ERASTUS WOODWARD, of Boston, in the county of Suffolk and Commonwealth of Massachusetts, and MATTHIAS BROOK, of said Boston, have invented an Improvement in Gang Pegging-Machines, of which the following is a specification.

, This invention relates to a class of driving devices which weterm group or gang pegging-machines.

It is important for various purposes, and especially for securing the edge of an upper to the insole in the lasting process, to drive simultaneously a group or gang of pegs without changing the position of the driving mechanism in relation to the work, or viceyersa.

We have illustrated, therefore, our invention as applied to a machine for driving the pegs necessary in securing the edge of an up-' per to an insole at the toe and heel in the saidlasting process.

It comprises, first, means for driving and withdrawing a gang of awls; second, means for operating a gang of driving-rods; third,

' means for feeding pegs to the gang of drivingrods; fourth, means for changing the location of the nozzles in relation to the work after the gang of awls has been operated and beforethe pegs have been driven; fifth, means for adjusting the nozzles horizontally; sixth, means for presenting this mechanism, or any part of it, to the work or surface in or upon which the pegs are to be driven.

In the drawings, Figure 1 represents a side elevation d our device in position for the commencement of its work. Fig. 2 is also a side elevation, representing the pegging devices upon the last. Fig. 3 is a plan with the machine upon the last. Figs. 4 and 5 are sections illustrating the means for the horizontal adjustment of the machine; Figs. 6, 7, and 8 represent the change in the position of the nozzles in relation to the surface of the work while the machine is in operation. Fig. 9 is a detail representing in elevation the feedways through which the peg-strips are fed to the feed-rolls. Fig. 10 is a side elevation, with a portion of the machine removed to show the operating mechanism. Fig. 11 is a vertical central section and elevation. Fig. 12 represents means for operating the transferring lifting-foot. Figs. 13 and 14 are detail views. We show as one means for supporting the feeding and driving mechanism, and for presenting it to the work, the standard A, which may project from any portion of the lastingmachine proper, or from a table or bench, upon or to which, orto the arm or pin a. projecting therefrom, is hung the frame B, having the counter-balance b and the bracket b. This bracket supports the arm 0, which is pivoted at c to the frame B. It carries the case G and the shell 0 within and to which the operative parts of the driving mechanism are secured.

The gang of awls D and the gang of drivers E are each provided with reciprocating movements in the nozzles F, there being a drivingrod and awl for each nozzle.

The nozzles are divided into two series, (one only of whichis sho Wn,) and are supported upon the plates f, the plates being hinged to each other at f.

The awls are divided into two series, to correspond in number with the nozzles in which they play, and are fastened, respectively, to the blocks D, which are pivoted upon the line f, to open or close with the nozzle-carrying plates.

The awl-carrying blocks slide horizontally upon the cross-head (1, attached to the lower end of thebar d and project within the horizontal recesses (Z in said blocks. The cam d on the shaft G reciprocates said crosshead. These awl-bearing blocks thus slide horizontally to and from each other, and are supported and operated by the cross-head d, which is itself reciprocated by the cam (1 upon the shaft G and the bar (1 Each awl-carrying block is provided with guides 62*, which slide upon the ends of arms H.

, The driving-rods E are carried by the blocks E, pivoted or hinged to each other, and play upon the arms H and the cross-head c, in a manner similar to that of awl-carrying blocks. As these driving-rod-snpporting blocks are .arranged upon a line with and immediately below the awl-carryin g blocks, it is necessary that the same should be provided with a series of concentric slots, through which the awls pass.

The cross-head a is fastened to the end of l the bar 0, and is reciprocated by the camgroove 0 in the disk 0 and the shaft G, and in which the cam-pin 0 upon the bar 0 plays.

It will be observed that the driving-bar d is arranged to straddle its operative cam 01 and that it is further provided with the bearings d in the upper and lower'portion of.the cam-carrying ease. The reciprocating bar 0 is also provided with like bearingin said case.

Each peg-strip I is fed through its respective feedway K by means of the feed-wheel M, which bears upon the upper edge of each )eg-strip, and is supported upon a shaft having bearings in the bracket m. These feedwheels are provided with an intermittent revolution by means of the lever m pivoted at m to the block or), operated-by the cam-projection m, projecting from the driving-block E through the pin on, to engage with the pinion m upon the end of the feed-wheel shaft m by means of the pivoted pawl m and springs m and m".

The device for severing the pegs from the peg-strips consists of the knife or knives N, fastened to the driving-rod blocks E, to reciprocate in the slit a across the feedways K. The cut pegs are advanced from this slit through the continuation of the feedway by the feeding of the peg-strips to a posit-ion in each nozzle beneath the driving-rods, as indicated in Fig. 10.

To provide the necessary horizontal adjustment to the driving -rod' and awl-carrying blocks, feeding mechanism, &c., we have caused the arms H, uponwhich said blocks are reciprocated, and the curved sliding plates H, from which said arms project, to have a movement to and from each other within the shell 0 by means of the racks h and pinion h upon the end of the spindle k having a b'earing, 0 in the shell, and operated by the disk-handle h. These curved plates'H are secured to the shell Why the guideways 0, and are provided with projections H one from the under side of one plate, and the other from the upper side of the other plate, to extend by each other to carry the operatingracks.

To effect the proper transfer by which each driving-rod and its respective portion of each nozzle is brought in line with the holes previously made by the awl, we have provided a transferring-arm, O, which is reciprocated at the properinterval by the cam-groove oin the disk 0 on the shaft G.

The'transferring-arm is pivotedat 0 to the sliding block '0 and has a slight longitudinal movementagainst the stress of the spring 0 which surrounds the pin 0 and preferably is somewhat rounded at its lower end.

The block 0 is provided with a cam-pin, 0 and is reciprocated in the ways 0 upon the This transferring-bar operates, in connec-' tion with the cam-groove O in the disk 0 upon the shaft G through the connecting mechanism,consistingof the reciprocating bar- 0 with its cam-pin 0". link 0, and crank-1e ver 0", which lays hold of the rod 0 having a bearing in the pivoted arm 0, the slotted le-- ver 0, and the adjustable pin 0' to swing the" arm 0 upon the bracket b sufficiently to effect the carrying of the mechanism for the pun pose stated.

The cam-carrying shaft Grmay be operated by hand or power, as desired.

To provide asuitable horizontal adjustment of the pegging-machine in relation to and alongside of its work, the supporting-arm a may be extended any requisite distance from its standard, and the frame B may have a horizontal movement thereon substantially parallel with the last.

In adjusting the nozzle upon the margin of the upper, the folding slides at the toe or heel, as the case may be, may be used in properly locating them by being advanced against them. The nozzles in that case would be arranged along the outer edge of the plate. They may, if necessary, project through holes in the lasting-plates.

The operation of this device in connection with alasting-machine is as follows: The last, withthe upper thereon, is jacked in the lasting-machine, the upper fitted to the last by the lasting appliances, and its edge folded upon the surface of-the insole.

The pegging-machine having been adjusted to the curvature of the surface upon which it is to be used is then operated, and is caused to descend upon that portion of the margin of the upper which is to be secured to the insole, and may by its weight drive a gang of awls, in which case the awls must'protrude from the nozzles, as shown in Fig; 1, before the machine is dropped upon its work. The awls are then withdrawn, the machine slightly raised upon the transferring-bar 0, which rests upon the insole, by the cam-groove 0, the nozzles lifted from the upper, and a slight horizontal movement-in the direction of the transferringbar is effected for thepurpose of bringing that part of each nozzle through which the peg is driven into line with'th'e holes made by the awls. The nozzles are then lowered upon theupper, and the pegs, which have previously- .been fed to the nozzles by the strip-feeding devices, are driven simultaneously by the descent of the driving-rods.

The advantage which arises from driving pegs in this manner consists in the saving in time effected over the methods now in use ofdriving but one peg at a time, as a number of pegs can be thus driven in about the sametime that it takes to drive one in the old manner; and as the work is not adjusted to the machine or the machine to the work for each peg driven, a saving ofall that time which is necessary with the single peg-drivin g machine plate 0 and is secured thereon by the cross bar 0 formoving the work to the machinefor-eachpeg 'driven is obtained, as the machine is placed but once for the entire driven.
